(4+2)/(1+1)= 6/2= 3 is the slope

y + 2 = 3(x + 1)
y+2=3x+3
y= 3x+1

What is the approximate distance between the points (-5,1) and (-2,3) on a coordinate grid? Show me an example please

yaroslaw [1]

Answer:

$d=\sqrt{13}\ units$ or $d=3.61\ units$

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

$A(-5,1)\\E(-2,3)$

substitute the values

$d=\sqrt{(3-1)^{2}+(-2+5)^{2}}$

$d=\sqrt{(2)^{2}+(3)^{2}}$

$d=\sqrt{13}\ units$

$d=3.61\ units$

Find the length of the third side. If necessary, round to the nearest tenth.

schepotkina [342]

Answer:

4.5

Step-by-step explanation:

To find the hypotenuse of a right triangle, we use Pythagorean's Theorem which states that $a^{2}+b^{2} =c^{2}$ . Plugging in the values of the two legs given, we get $2^{2} +4^{2} =c^{2} =20$ . We can take the square root of each side and get that $c=\sqrt{20} =4.5$ .

49/10 as a mixed number

Anni [7]

⇒ $\frac{49}{10}$

$\frac{49}{10}$ is a improper fraction.
$\frac{49}{10}$ as a mixed number would be 4 $\frac{9}{10}$

⇒10 x 4 = 40
⇒40 + 9 = 49

$\frac{49}{10}$ = 4 $\frac{9}{10}$

⇒ANSWER = 4 $\frac{9}{10}$
